So your aluminum Series 2 or Series 3 Apple Watch is suddenly cracking around the edges… but you don’t remember bumping it on anything, or being particularly rough with it.

Surprise! It might not be your fault at all.

Apple says that they’ve determined that “under very rare circumstances”, the displays on aluminum Series 2 and 3 Watches are developing cracks that can wrap along the rounded edges.

The good news? If Apple determines your display crack is caused by this newly discovered issue, they’ll replace the screen for free. The bad news? It’s not the kind of thing they can fix at the Genius Bar, so getting it patched up means shipping the Watch to Apple and being without it for 5+ days.

(It sounds like the kind of cracks they’re looking for are pretty specific — they’re looking for cracks that developed around the rounded edges, as pictured above. So if you really just dropped something on the watch and the display got obliterated, you probably aren’t gonna be able to pull a fast one here.)

As spotted by MacRumors, Apple has a full list of watches that are going to be covered under this new screen replacement program here. The company says that all eligible aluminum Series 2 and 3 watches will be covered under this new screen replacement program for 3 years from its original retail purchase date, or one year from today — whichever is longer.
